Product Description
The IP-Ethernet® is part of the IndustryPack® family of modular I/O components. It provides modular Ethernet and IEEE 802.3 compatibility to a diverse number of host computer platforms through utilization of the IndustryPack Logic Interface.
Features:
- Am79C90 Local Area Network Controller for Ethernet (LANCE)
- Supports 10Base5 Type A (“Ethernet”); 10Base2 Type B (“Cheapernet”); and
10BaseT (Twisted Pair) network configurations.
- Sixteen Kbytes dual ported RAM for packet transfer.
- Sixteen bit IP data bus access to RAM.
- On-board DMA and buffer management, 48 byte FIFO.
- Network and packet error reporting.
- Back to back packet reception with as little as 4.1 μsec. interpacket gap time.
- Built in diagnostic support including: internal/external loopback; CRC logic
check; time domain reflectometer.
- Manchester encoder / decoder at 10 Mhz.
- Guaranteed carrier and collision detection squelch threshold limits: carrier /
collision detected for inputs > -275 mV; no carrier/collision for inputs < -175 mV.
The IP-Ethernet is a two-board set consisting of a single-wide IndustryPack and one of three available transition modules. Interconnection between the two boards is accomplished by a 50-pin ribbon cable. Figure 1 below illustrates the typical arrangement of IP, Carrier board and transition module.
